Potent but ill researched. Despite promising antiproliferative data of substituted xanthones, their structure-activity relationship remains largely unknown. We systematically synthesized previously inaccessible phenyl- and chloro-bearing x...

Crystal structures of 1-methylpseudouridine alone and as part of short RNA oligos were recorded. The latter ones are at a resolution of up to 1.01 Angstroem. They show that minimal structural distortion is observed with respect to non-modified RNA.
Abstract
All widely used mRNA vaccines against COVID-19 contain in their sequence 1-methylpseudouridine (m1Ψ) instead of uridine. In this publication, we report two high resolution crystal structures (at up to 1.01 and 1.32 Å, respectively) of one such double-stranded 12-mer RNA sequence crystallized in two crystal forms. The structures are compared with similar structures which do not contain this modification. Additionally, the X-ray structure of 1-methyl-pseudouridine itself was determined.
